This video was interesting.
Anywho, The check doesn't even have to be clean, so long as it slides off your leg or doesn't catch you with the weight on it. Doesn't seem like it should draining the amount of stamina it does when you try to defend it, and that forward rushing rushing combo should be what you're able to do if you successfully check/side step the oblique kick, rather than get poked to death.
So this idea that the oblique kick can't get checked is ridiculous to me. Maybe not damaging like the regular check, BUT their foot will either hit your shin or bent knee. Way better than the alternative.
Oblique kicks can also be countered with teeps quite well if the kick is coming from the rear leg (Jones Vs. Rampage style, but I rarely see people doing that). Again, you're catching him off balance, so bracing your balance and countering with a solid teep will even push him to the ground. If they could add that feature with teep kicks against oblique kicks, or extra vulnerability, that can work too.
*Edit*: From Jack Slack : "a good rule when dealing with low kicks is to pick the leg up, make sure it's bent, and point your knee and the front of your shin towards the kick. You'll take the brunt on the hardest part of your shin, and if your leg is bent and your foot off the floor, there is no chance of hyper extending your knee. It's the difference between attempting to break a board that is braced at both ends, and a board which is suspended from one end and free to move around."
Shouldn't be too hard to get an animation like that, that doesn't drain an absurd amount of stamina. It'd be different if you could use more angles in this game, but that isn't the case.

The first takedown scored on Jones in his entire career came as Gustafsson parried one of Jones' straight kicks and capitalized. Even Jon Jones can't give up dominant positions so easily, and following this counter he threw his straight kicks far less frequently.
